Bug 1213: Refine changes .. comments and API
- Use InterruptSource.Thread.create(..), while reducing InterruptSource.Thread ctors to 3 variants. - Use InterruptSource.Thread instead of java.lang.Thread where possible - Use SourcedInterruptedException where possible - SingletonInstanceServerSocket: start(), stop() and run() - Persistent-Wait and Cancelable - Add @since 2.3.2
